Kafka-node client keeps sending request to broker which went down

When a broker host goes down/restarts, the kafka client keeps sending the new requests to the same hosts. As a result, the requests are failing with this error: Request timed out after 30000ms.

Node version: v6.8.1
Kafka-node version: 3.0.1
Kafka version: 2.11-2.0.0
Number of Brokers: 3
Number partitions for topic: 10

Some code pointers:

"clusterConfig" : {
  "kafkaHost": "localhost:9092,localhost:9093,localhost:9094",
  "autoConnect": true
}
...
let kafkaClient = new kafka.KafkaClient(clusterConfig);
producer = new kafka.HighLevelProducer(kafkaClient, cluster.producerConfig);
Promise.promisifyAll(producer);
...
producer.sendAsync([eventPayload])
  .then(function (data) {
    let topicName = eventPayload.topic;
    let payLoadSize = (eventPayload || '').length;
    logger.eventInfo(topicName, payLoadSize, source);
  })
  .catch(function (e) {
    logger.produceFailedEvent(eventPayload, source);
    throw Error.getErrorObject(errorType, e, topic, source);
  });

I have the kept the other configurations to default. Please help in resolving the issue.

Thanks, Shashank
